Low-power refers to electronics that are designed to use less power than their common counterparts. This is often a requirement because of limited available power, as in battery operated devices, or in cases with limited cooling capabilities, as in notebooks.

Why is my measured leakage current of the capacitors much lower than my calculated value?
This is more a theoretical question.
I have a DC circuit with multiple capacitors with different voltages.
Because I need to know how much current my circuit needs over a longer time, I calculated all …

Decoupling Capacitor on GPIO instead of connected directly to battery
I am building a device that is for most of the time in sleep mode. When woken up, I am sending some BLE signals and use a LED. To support the battery I have a 2u2F capacitor.
But because my battery is …

Use a MOSFET to switch on/off power supply for a low power microcontroller
I am trying to develop a circuit that can switch on and off the power supply for a microcontroller. I have around 0.2 - 0.7 V which I can generate to control the electronic switch.
My idea was to use …

Use a MOSFET to switch on/off power supply for a low power microcontroller
Thank guys. So I did a new simulation, based on your answers:
v_photodiode is my photodiode which is giving pulses of 0.7V for around 3 seconds.
It looks already better now :)
The problem now is that …
